Legal claims defining the scope of protection. Each claim is shown in both the original legal language and a plain English translation.
1. A wireless communication system comprising: a plurality of relay devices which are connected to one another via a communication line and to which unique relaying channels are respectively allocated; and a plurality of wireless terminal devices which communicate with each other via at least one of the plurality of relay devices, each relay device of the plurality of relay devices transmitting control information to each wireless terminal device which is registered in the corresponding relay device, and each wireless terminal device selecting, based on the control information received from the relay device which registers the corresponding wireless terminal device, a channel that is currently able to relay a communication among channels allocated to the respective relay devices to establish a communication between the wireless terminal devices, wherein a second relay device of the plurality of relay devices has information on the wireless terminal device registered in a first relay device of the plurality of relay devices beforehand, and the wireless terminal device registered in the first relay device has information on the second relay device beforehand, and further wherein when the first relay device becomes unable to transmit the control information, the second relay device transmits, instead of the first relay device, the control information to the wireless terminal device registered in the first relay device, and the wireless terminal device registered in the first relay device receives the control information from the second relay device.
A wireless communication system has multiple relay devices connected by a communication line, each with a unique relay channel. Wireless terminals communicate through these relays. Each relay sends control information to its registered terminals, and each terminal selects a relay channel for communication based on this control information. A second relay stores information about terminals registered with a first relay, and the terminals store information about the second relay. If the first relay fails to transmit control information, the second relay transmits it instead to the first relay's terminals, enabling continued communication.
2. The wireless communication system according to claim 1 , wherein when being unable to receive a signal regularly transmitted from the first relay device via the communication line even after a predetermined period has elapsed, the second relay device transmits, instead of the first relay device, the control information to the wireless terminal device registered in the first relay device.
In the wireless communication system described in Claim 1, if a second relay stops receiving a regularly transmitted signal from a first relay over the communication line for a set period, then that second relay takes over transmitting control information to the wireless terminals that are registered with the failed first relay. This failover ensures continuous control information delivery to the terminals.
3. The wireless communication system according to claim 1 , wherein when being unable to receive control information from the first relay device even after a predetermined period has elapsed, the wireless terminal device registered in the first relay device receives the control information from the second relay device.
In the wireless communication system described in Claim 1, if a wireless terminal fails to receive control information from its registered first relay device for a specific amount of time, the terminal begins receiving control information from a pre-configured second relay device, allowing continued communication. The wireless terminal independently switches to receiving the control information from the second relay upon detecting the failure of the first relay.
4. A wireless communication method of a wireless communication system comprising a plurality of relay devices which are connected to one another via a communication line and to which unique relaying channels are respectively allocated, and a plurality of wireless terminal devices which communicate with each other via at least one of the plurality of relay devices, each relay device of the plurality of relay devices transmitting control information to each wireless terminal device registered in the corresponding relay device, and each wireless terminal device selecting, based on the control information received from the relay device which registers the corresponding wireless terminal device, a channel that is currently able to relay a communication among channels allocated to the respective relay devices to establish a communication between the wireless terminal devices, wherein a second relay device of the plurality of relay devices has information on the wireless terminal device registered in a first relay device of the plurality of relay devices beforehand, and the wireless terminal device registered in the first relay device has information on the second relay device beforehand, and further wherein when the first relay device becomes unable to transmit the control information, the second relay device transmits, instead of the first relay device, the control information to the wireless terminal device registered in the first relay device, and the wireless terminal device registered in the first relay device receives the control information from the second relay device.
A wireless communication method for a system with multiple relay devices connected via a communication line, each with its own relaying channel, and multiple wireless terminals communicating through these relays. The method involves each relay sending control information to its registered terminals. Terminals choose a relay channel for communication based on this control information. If a first relay fails to transmit control information, a second relay (which has information on terminals registered with the first relay) takes over, transmitting the control information to those terminals instead. The terminals registered with the first relay also have information about the second relay and can thus receive the control information, thus maintaining wireless communications.
